Since its a z71 and being a 4x4 you
take 71 and subtract the number of
cylinders you have which should be
8 to get 64. Then take 4 and multiply
it by 4 "4x4" to get 16. Subtract 16
from 64 to get 48. Jeff Gordon drives
the number 24 car so you take 48
and divide by 24 to get 2. Your truck
has 2 axles.
